Perhaps router vendors can figure out some way to ensure that all

Our routers have been assigned IP numbers from our CIDR blocks for some
time now. 

We are considering assigning IPs for router interfaces from our allocated
swamp, broken up into numerous small /30 subnets (or similar).

Any comments on this practice?
